`cib` doesn't work at the start of a line, while `ci'` does

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Be in normal mode editing the line "this is (a test)", with your cursor at 
the start of the line
2. type `cib` or `ci(` from normal mode

What is the expected output? What do you see instead?
I should be in insert mode with my cursor right after the (now empty) parens, 
like this: "this is (|)" where '|' is the cursor

Please provide any additional information below.
I'm not sure if this wasn't implemented because parens and braces sometimes 
span multiple lines, but `ci'` doesn't work on multiple lines, and I don't 
think it really has to, but I would like this to work for other text objects.  
I'll see if I can't whip up a patch, but don't hold your breath because I 
haven't done C in awhile!

This is intentional. It's no just about multiple lines, it's about nesting. 
Consider

1. if (
2.   a &&
3.   (b || c) &&
4.   d)

If you place the cursor at the beginning of line 3, vab will select text on all 
four lines, because the cursor is immediately inside the parenthesis block 
starting at line 1 and ending at line 4. If your suggestion is implemented, 
only "(b || c)" on line 3 would be selected. This would break things in 
annoying and unexpected ways for things like =ab in C code.

Gotcha.  I guess I'm not acquainted with the internals of how textobjects work, 
so I didn't think about how it might break other features.  Thanks for the 
info, feel free to close :)
